一、主机系统故障
PLC维修时, 主机系统最容易发生故障的地方一般在电源系统和通讯网络系统,电源在连续工作、散热中,电压和电流的波动冲击是不可避免的。通讯及网络受外部干扰的可能性大,外部环境是造成通讯外部设备故障的最大因素之一。 PLC维修时,系统总线的损坏主要由于现在PLC 多为插件结构,长期使用插拔模块会造成局部印刷板或底板、接插件接口等处的总线损坏,在空气温度变化、湿度变化的影响下,总线的塑料老化、印刷线路的老化、接触点的氧化等都是系统总线损耗的原因。所以在系统设计和处理PLC维修系统故障的时候要考虑到空气、尘埃、紫外线等因素对设备的破坏。目前PLC 的主存储器大多采用可擦写ROM,其使用寿命除了主要与制作工艺相关外,还和底板的供电、CPU 模块工艺水平有关。而PLC 的中央处理器目前都采用高性能的处理芯片,故障率已经大大下降。PLC维修时, 主机系统的故障的预防及处理主要是提高集中控制室的管理水平,加装降温措施,定期除尘,使PLC 的外部环境符合其安装运行要求;同时在系统维修时,严格按照操作规程进行操作,谨防人为的对主机系统造成损害。
二、I/O 端口故障
PLC维修时,PLC 最大的薄弱环节在I/O 端口。PLC 的技术优势在于其I/O 端口,在主机系统的技术水平相差无几的情况下,I/O 模块是体现PLC 性能的关键部件,因此它也是PLC 损坏中的突出环节。要减少I/O 模块的故障就要减少外部各种干扰对其影响,首先要按照其使用的要求进行使用,不可随意减少其外部保护设备,其次分析主要的干扰因素,对主要干扰源要进行隔离或处理。
